Compare Analyses Of Ultrasound Representation And Pathology In Breast Tumor

Objective: Detected the breast tumors by elastosonography and Color dopplerenergy(CDE), and compare the result with the pathology results after operation. Theninvestigate the value of elastosonography and Color doppler energy(CDE) in theestimating of the benign or malignant of breast tumors and provide informations forthe clinical treatment.Methods:80cases of breast tumor patients (96lesions) was collected from the FirstAffiliated Hospital of Henan University of Science and Technology since September2010to September2011. All patients routine examination by color Doppler ultrasoundpreoperative. The patients took a supine or left and right lateral, and fully exposed tobilateral breast, using high frequency linear vibration probe coated with a sufficientnumber of medical ultrasonic coupling agent, with direct scanning method to nipple asthe center radial scanning, careful examination of bilateral breast and found that breastlumps, color power Doppler flow imaging careful observation of the mass peripheralblood flow within the classification given in accordance with the number of lumps inand around the blood flow signal, and record the mass of color Doppler flow signalgrading. Then switch to the ultrasound elasticity imaging mode, using two-dimensional ultrasound and ultrasound elastography double the rate of real-timedisplay mode, the probe touch the lesion of the breast where the surface of the skin,the probe direction, the mass where the parts of the breast surface of the skin tomaintain the vertical, while observing the ultrasound two-dimensional images andultrasound elastography images, and adjust the elasticity imaging region of interestcorresponding records sampling frame size is about2to3times of the breast lesions,ultrasound elastography score. And record the save, and the comparative analysis withthe pathologic results.Result: Pathological findings in80cases of breast tumor patients (96lesions):56lesions of invasive ductal carcinoma,11lesions of breast adenosis,24lesions of the breast fibroma,3lesions of intraductal papilloma,1lesion of granulomatousinflammation with necrosis,1lesion of fibroadenoma with mucous necrosis; colorpower Doppler Adler semi-quantitative method flow grade results:28lesions of0tograde Ⅰ and grade Ⅱ～Ⅲ grade68lesions, color power Doppler Adler semi-quantitative method flow grade0～I level diagnostics for benign lesions, grade Ⅱ～Ⅲ level diagnosis of malignant lesions, sensitivity was94.6%, specificity62.5%,Youden’s index was0.571, and the accuracy was81.3%; the results of ultrasoundelastography score:≤3points was52lesions, and≥4points was44lesions, ultrasoundelastography score≤3points diagnosis of benign lesions,≥4points diagnosis formalignant lesions a sensitivity of73.2%and a specificity of92.5%, Youden’s indexwas0.657with an accuracy of81.3%. Color power Doppler flow grading andultrasound elastography score combined sensitivity of94.6%and a specificity of92.5%, Youden’s index was0.871, accuracy was93.8%.Conclusion: Ultrasound elastography based on the relative hardness of the tumor andsurrounding normal breast tissue within the breast to determine the breast tumor ofbenign or malignant nature it has lower sensitivity, but has higher specificity; colorpower Doppler imaging based on the blood of breast massthe richness of the flowsignal good judgment breast lumps, evil nature, it has high sensitivity, but specificitywas slightly lower; combination using ultrasound elastography and color powerDoppler imaging can improve the sensitivity, accuracy.
